NCIt definition : Alanine-tRNA ligase, cytoplasmic (968 aa, 107 kDa) is encoded by the human AARS1
gene. This protein plays a role in the ligation of alanine residues to transfer RNA(Ala).;
Alternative definition : CDISC: An antigen encoded by the AARS1 gene that regulates alanyl-transfer RNA synthesis
(attaches alanine to tRNA). It can be considered as an autoantigen and is commonly
associated with the autoimmune diseases anti-synthetase syndrome, polymyositis and
dermatomyositis.;
NCIt note : Alanine-tRNA ligase, cytoplasmic is a target for autoantibodies in the autoimmune
diseases polymyositis and dermatomyositis.;
